Started at Logan Pass and headed up Hidden Lakes Trail. The first half of this trail goes only to the Hidden Lakes Overlook and is largely boardwalk and stone steps. The treadway was nice and there were TONS of people. The (boardwalk supported) overlook was great, but it became immediately clear that 95% of the people turn around here. [Later confirmed by a ranger who said that about 2000 people visit the overlook in a day at this time of year, but less than 100 will descend to the lake.] As we started off to the lake, a gentleman coming from the other direction, said, "If you go another 200 feet up the trail, you'll see a mountain goat." Sure enough, he was right. A crowd of about a dozen watched as the goat nibbled, tried to climb a small tree, and generally tried to look cute.
After I took this photo, I turned around and saw a marmot running from some scrub pine. A moment later, a small black shape bounded after it, and a moment later, the marmot's new name was, "Lunch". While the goat was 3-4 meters away from me, this was more like 60 meters away, so there is a good bit of zoom here.
After all of the animal excitement, we hiked down to Hidden Lake. We were the only visitors the entire time we were there, but we did see some folks on the trail both ways.
Couldn't beat the day for hiking, though.
